Warning : Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not
stare into beams or view directly with optical instruments.
Warning : Use of controls, adjustments, or performing procedures other than those specified may
result in hazardous radiation exposure.
Warning : Hazardous voltage or energy is present on the backplane when the system is operating.
Use caution when servicing.
CAUTION : To prevent ESD damage, wear grounding wrist straps during these procedures and
handle modules by the carrier edges only.
CAUTION : Make sure that you do not accidentally press one or more of the ejector release
buttons on a switching, supervisor, and fabric modules. These buttons and their mechanical levers
are designed so that you can easily power down and remove these modules when you need to
replace them. If you press one of these buttons, the lever for that button releases from the front
of the module, but the module remains operational and connected to the system. If you press the
other ejector button on the same module at the same time as you press the first button or while
the lever for the first button is released, the lever for the second button releases, and the module
powers down and disconnects from the system.
This behavior can be disabled with the no hardware ejector enable command. To minimize the
chance of accidentally disconnecting a module with a released lever, press the lever back toward the
module until it clicks. If both levers are released, the system has disconnected and powered down the
module, and the STATUS LED will be unlit. To reconnect and power up the module, either remove and
reinsert the module in the chassis or close the lever and use these system commands: out-of-service
module and no poweroff module.
Note : Install the IBM c-type SAN Device chassis in the rack before installing modules. See the Wire-
stripping tool to remove the insulation from the grounding wire.
Note : In systems with redundant supervisor modules, you can replace the faulty supervisor while the
system is operating, provided that one supervisor is always operating.

Installing Supervisor Modules

About this task
Note : You need a flat-blade or number 2 Phillips-head screwdriver to loosen or tighten the captive screw
on the supervisor module.
Use this procedure to install a supervisor module on a IBM c-type SAN Device.
Procedure
1. Before installing any modules in the chassis, we recommend that you install the chassis in the rack.
See the "Installing the SAN384C-6 or SAN768C-6 Device on a Four-Post Rack or Cabinet" on page
66.
2. Verify that there is enough clearance to accommodate any cables or interface equipment that you
want to connect to the module.
